Couldn't  you check the runtime folder you down loaded for the appropriate locations and entries?
Perhaps you've got some textures and were expecting a character or prop or vice versa???
Just did that my self recently and went back to the original file to see what exactly was in there.
What I was expecting was not there, so hence, I couldn't find it in my runtime. I would guess the
read me would give a file and location listing also.

While I'm here, want to say thanx for doing some "interesting" freebies. Good Stuff.......
And thanx to some nice staff person who helped me straighten that out.......
